IMPROVEMENT IN LOOMS FOR CROSS-WEAVING.

Specification forming part of Letters Patent No. 50,990, dated November 14, 1865.

lframes having eye-pointed thread-guides for carrying thewarpth`reads, thsaid frames being operated in the manner described hereinafter, so as to produce ornamental fabrics.

In order to enable others skilled in the art to make and use myinvetition, I will now proceed to describe its construction and operation.

-On reference to the accompanying drawings, whichform a part of this specification, Figure l is a front elevation, partlyjn section, oi'

.sufficient of a loom to illustrate my improvement; and Fig. 2,-a section on the line l 2, Fig. 1, looking in the direction of the arrow. y

A and A are the side frames of the machine, which are connected together by the cross pieces B, B', C, l), and E. In the side frames turns the crank-shaft F for operating the lathe G by means of the rods a in the usual manner, the lathe carrying the usual shuttle and reed.'

To one side oi' the frame A, near the upper end of the same, is hung a toothed segment, H, the teeth of which gear into those ot' a pinion, b, on the end ofthe heddle-shaft I, which turns in the opposite side frames of the machine.

At one side of the segment H is a slotted projection, c, and at the opposite side a projection, d, to which is jointed the upper end of a rod, J, the lower end of the latter being connected to a cranic-wneel, K, on tne end of the drivin g-shai't F.

To brackets on theinside ot' the frame A are hung levers L and M, levers L and M being hung to brackets on the opposite frame, and in the lower end of each lever is a recess adapted for the recept-ion ot' the edge of one 'of two heddle-i'rames, N or O, the iornier being hung to the ends of cords c c, which passaround the shaft l, and the latter io the opposite ends of said cords, the levers L and M heilig main tained against the edges ot' the frames by springs f.

" To the lower edge of the frame N are connected the ends of the cords e', which are passed round the cross-bar E and connected at their ,opposite en ds to the lower edge of the frame O, this arrangement ot the trames in the inachine being similar to that of heddlc-frames in ordinary looms.

In projections on the inside ot' the frame A turns a square spindle, P, projections i i" on which bear against the.; upper ends of the levers L and M, and at the end ofthe spindle is aratchet-wheel, to which is adapted the hooked end of a pawl, m, hung lto one arm of a bellcrank lever, Q, the other arm of the latter passing through the slot in lthe projection c ot' the segment H.

From the upper side ot' the heddle-frame O, project (downward) anumber ot' thread-guides, n, and from the under side of the frame N project (upward) a number o' similar threadguides, u', one ot' the warp-threads, .r or

passing through each oi.' these guides.

As the crank-shaft F is turned the lathe is moved back and forth, a vibrating motion is imparted to the segment H, and the shaft I is rotated tirstin one direction and then in another', so as to alternately raise and lower each of the frames N and O. As the segment H vibrates a similar motion is imparted to the bell-crank leverQ,the pawl mof which gears into the teeth of the ratchet-wheel on the end oi the block P and turns the latter one-fourth of a revolution at each vibration. As the projections i i are brought into contact with the upper ends of the levers L and M the latter will be caused to vibrate and impart a longitudinal reciprocating motion to the frames N and O. It will be seen, however, that the projections i and i are so arranged that when one of." the levers is moved the other will remain stationary, so that the frames N and O are never moved together in the same direction.

When the machine is put in operation and the pawl m is thrown out of gear with the ratchet, so that the frames N and O have only a vertical reciprocating motion, the threads .r and fr will be crossed vertically and the shuttlc-thread will be thrown between them, as in and imparta longitudinal motion to the frames the threads a: w will be opened for the passage ofthe shuttle, as before; but priortothe threads being opened in the opposite direction one of the frames, N or O, is moved longitudinally a sufficient distance to carry the upper threads over the lower ones, so that the threads after passing up at one side of the threads w', are carried over the latter and pass down on the opposite sides of the same, after which the shuttle-thread is passed between them, as before.

1t wilt be apparent that the style of the fabric may be altered by increasing the length of the projections i i', so as to move the frame suiciently to carry each upper. thread over two or more of the lower ones, and that, if desirablem pattern-chain may be hung to the shaft P, so as to prodncefabries of more elaborate patterns. In someinstances, also, two or more frames may be used in place of leach of the frames N and O, so that a portion of the lower Warp-threads, rv, may be moved in one direction anda portion in another, the upper warp-threads being operated on in a like inanner, the character of the fabric thus produced being determined by the number of frames employed and the manner in which they are operated.

I claim as my invention and desirerto Secure lby LettersPatent--- jections 1', the whole being arranged and operating substantially as and for the purpose herein described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
